Every day, turning on the computer and opening the web page has a particularly magical feeling. All kinds of unreliable ideas that you once imagined crazily in your childhood are always seriously discussed in the dark corner as a major event to save the country and the people. For example, Mr. Mou's ideal is to blow a 50-kilometer hole in the Himalayas, introduce warm air from the South Pacific, and turn the Qinghai-Tibet Plateau into a land of plenty. Later, Ge You made this joke "Be there or be square". People in the cinema were laughing their heads off at that time-I dare think.

Another example is to lead the water from the Bohai Sea to the Taklimakan Desert. This is a seminar that has just been held recently, and some experts have given suggestions, and some have said that it can be realized within six years. Anyone with a little common sense probably knows that the problem of land salinization caused by seawater in coastal areas has not been solved. If seawater reaches the mainland, salinization will only get worse. Moreover, due to the special topography of Xinjiang, even if the surface runoff is increased, the evaporation may not be increased.

Large evaporation does not mean large rainfall. At that time, lakes in the hinterland of Xinjiang, such as Lop Nur, had a surface area of 3,000 square kilometers in 1942, but they dried up after 1972. Lop Nur is large enough, but it has not affected the rainfall in Xinjiang. Lop Nur dried up because the inflow of Tarim River dropped sharply. There are more than 130 reservoirs and more than 400 pumping stations in the whole Tarim River. This is the reason why Lop Nur disappeared.

It is not that there is no surface runoff, but that the surface runoff is destroyed artificially, which leads to unscientific utilization of water resources. Xinjiang is not a flood-prone area, and the main purpose of dam construction is to generate electricity. Now that there is less water, it is brewing to transfer water from the east. This kind of thinking is not a problem-solving thinking. If you make a mistake, you don't go to the root cause, but you have to make another mistake to make up for the last mistake, which is tantamount to robbing Peter to pay Paul.

You can think about it. On a huge map of China, the middle route and the east route of the South-to-North Water Transfer Project are two grand canals, which transfer water from Danjiangkou and Yangzhou to Beijing respectively. If a new project is added to introduce the Bohai Sea into China, it will be a Grand Canal, which contradicts the basic characteristics of China's topography, such as high in the north, low in the south, high in the west and low in the east. In terms of traffic conditions, it is bound to consume a lot of electricity. Experts say that it is basically not feasible to use seawater to generate electricity in the gap. If they are willing to look at the structure of the turbine, they will certainly regret saying so.

Let's talk about things that have been diluted. Although the seawater desalination technology in China is very mature, it can only produce about 500,000 tons of seawater every day, which is mainly used in coastal industrial enterprises, accounting for about 1% of the world total. This figure is relatively small because the pricing mechanism and incentive mechanism of seawater desalination have not yet formed. The cost of South-to-North Water Transfer to Beijing is about one ton 10 yuan, and the fresh water transferred here is much more expensive than the local groundwater. A while ago, Beijing was still studying the issue of desalination into Beijing, but desalination water is more expensive than water transfer, so it had to be put on hold for the time being. This problem in Xinjiang is more complicated. Adjusting seawater has both distance cost and desalination cost, which can only be more expensive.

Moreover, Bohai Bay is a semi-closed sea area with serious pollution, poor mobility and high cost of seawater desalination. The places where seawater desalination is done well in the world are places where seawater is relatively clean. If the water from Bohai Sea is transferred to Xinjiang, the concentrated brine produced during seawater desalination is simply unbearable for the sewage purification system in Xinjiang, and the cost is higher than the above analysis. If the water price is opened, it will be an astronomical figure for water users and enterprises.

Experts clap their thighs and heads, and basically don't settle accounts. Many people applaud according to the topics stipulated by the organizers, regardless of the actual feasibility. This level is not much different from that of Mr. Mou. Any idea that I can think of "pasting the Great Wall, railing the Pacific Ocean and setting the equator with gold". This idea was originally mainly to fool the leaders, but after being reported by the media, it became a fool for the people. The broad masses of the people must not be fooled by this handful of experts.
